U+Japan's Nail is a nail salon at 150 Orchard Road, Orchard Plaza #03-67, Orchard, Singapore. Google reviewers rate it 4.9 out of 5, from 96 reviews, a strong result for a salon of this kind.
A good nail salon is judged on hygiene and on the care taken with the detail work. Look for tools that are sealed or sterilised in front of you, and a clean, orderly workstation. Ask what the quoted price covers before you agree, since a basic manicure, a gel finish and nail art can add up quite differently. Many people find it helps to bring a photo of the shape and colour they want and to say how long the finish needs to last. Booking ahead is usually sensible, particularly on weekends and before public holidays.
The salon is in Orchard Plaza on Orchard Road, a shopping centre, so it suits people already in town for shopping or meals.
